The resulting accavations s6ould be bsck6lled with compected <br />structucal fill. <br />• Compect structurel fill in building md pavement preas W at Iwt 95 percent of modi8ed <br />Proctor ma�rimum dry dendry. Fill more thect 1 foot below �ubgrade �hould be compected <br />to 90 percent of this value. Plsa stnutural fill in IiRa of not more thm 8 inc6es loox <br />tbickness, at a moisture oontent within 2 percent of optimum, and cwmpect wifomily with <br />suitable equipr►rnt. <br />Bnilding Fonnd�Hone <br />� Conventional, shellow speead and continuous footings should be designed for 2,500 psf <br />maximum, net, allowable soil bearing capsciry on properly compacted structural fill over <br />fien netive soil or on fiim, eative, silry sands encountered ebout 4 to 7 feet below exisdag <br />Brade• . <br />• Subsurface drains should be provided around foundations. <br />r � •• • ; <br />Tha authoriud scope of services perfom►ed by Gllss for this projxt included a viaual site <br />reconnaissance, subsurfaa exploration wnsisting of 3 augered borings, limited laboraWry testing, <br />geotechnical enginaring analysw, and preperarion of thia rcport. Work wes performed �s described in <br />Giles' proposal number 6GP-961203 and authori�al by the McCabes on Janusry 22,1997. 'I1u pucpox <br />of this study wes to establish genecal subsurfece conditions from wtuch conclusioar end <br />recommendations regerding foundation design and eadhwork construction could be focmulated. Glfes' <br />scope of services did not include the collection or testing of soil or water semples for contamination by <br />hazardous or dangerous materials. <br />This repo�t has been prepered in accordence with generally acceptcd geotechnical da+ign practice <br />" and has been prepared for the exclusive use of Dan and Trish McCabe and their agent� for specific <br />application to this project. The recommenciadons contained herein are based in put on preliminery <br />project infortnation provided to date to Gi(es which included a preliminary building layout It is <br />recommended that final design drnwings and specifications t+e nviewed by Gilts to verify that the <br />recommendations wntained in this rcport have ban incorporated into the design. <br />
